' which provision is made for collecting and i Patented May 6, 1930 PATENT ERANK-H. RYDER, OF COBLESKILL, YORK, ASSIGNOR T0 BARBER REFRIGERATEUR CORPORATION, A CORPORATION OF NEW YORK :aurait-inneren Application filed March 1, 1929. Serial No. 343,590.

My invention is particularly directed to an improved construction `of ice refrigerators. The invention contemplates a construction in `/draining any moisture condensed on the outer surface of the metallic ice chamber wall be tween the ice chamber wall and the refrigerator wall.

In refrigerator constructions,-it is the gen eral practice to form the back, side walls and pan of the ice chamber in a. unitary structure.

' This is sometimes done, for example, by forming the rear wall and the bottom or pan member from a single piece of galvanized sheet iron with their edges flanged and overlap ping the sides which are separate members suitably secured in place, the front edge of the bottom being finally turned up and secured to complete the pan. In the assembled refrigerator, the one side wall and the back wall are in direct contact with the composite wall of the refrigerator, usually there being interposed a layer of waterproof paper or similar material. v

Usually, the refrigerator wall is composed of wood with a lining of cork-board or other suitable heat insulating material, and the water-proof paper on both sides of the Lining.

`Despite the use'of the water-proof paper within the refrigerator wall, gaseous moi"- ture permeates through the wall and is condensed on the outer surfaces of the ice chamber wall. The water so condensed collects between the ice chamber wall and the refrigerator wall. This water of condensation is more or less absorbed by the wooden wall, and the swelling which results therefrom frequently assumes destructive proportions.

One of the purposes of my invention is to f prevent this absorption of the moisture of condensation by the wooden walls of the refrigerator. One way contemplated by my invention to accomplish this is to space the metallic ice Chamber Wall from the wooden refrigerator wall with its water-proof lining. While this may be done in various ways, I have found it satisfactory to utilize spaced strips of wood or other material of small heat conductive capacity, like furring strips, be-

tween the metal and wooden walls for the purpose.

My invent-ion also comprehonds means to dispose of this water of condensation, and this may be done by providing a construction in which the Water condensed on the outer surface of the ice chamber wall has a. free passage to the refrigerator drain. For example, the parts may be so designed that the ice chamber walls are contained Within and drain into the ice pan, in which case the ice pan is structurally separate from the side walls of the ice chamber.

A detailed description of one embodiment of my invention will be given in connection with the accompanying drawings in which F ig. l is a perspective of a refrigerator having partsbroken awayto show the construction ofthe ice chamber and `adjacent Wall section;

Fig. 2 is a iverticalsection through the refrigerator on the line 2-2 of Figure l, and

Fig.` 3 `is a horizontal section on the line 3&3 of Figure 2.

In the embodiment illustrated, the com positerefrigerator wall 1 consists of an outer wooden wall section 2, and a cork-board lining 3 which is wrapped in water-proof paper 4. Strips or cleats 5 are interposed against and secured to the inner face of the composite refrigerator wall and serve 4positively to maintain a space between the ice chamber and the refrigerator wall. The strips 5 are nailed or otherwise secured to the upper and lower cross pieces `6. Thelmetallic ice chamber 7 is placed in the refrigerator with the rear wall 8 against the strips 5 on the rear Wall of the refrigerator and the side wall 9 against the y end wall 10. `The rear wall 8 and the side wall 9 slope inwardly from thestrips 5 `from the top downwardly as will be hereinafter described.

`The ice chamber 7 is constructed hybending a single piece of galvanized sheet iron to form the baclr 8 and sides 9, 11. To form the bottom or ice pan l2, the edges of a piece of galvanized sheet iron, cut to the proper proportions, are bent upwards to form an obtuse `angle therewith and constitute sloping sides therefor. The joints at the corners formed by the turned-up edges or sides are Vsuitably closed in a watertight manner.

the pan at the front only thereof as clearly shown in the drawing. Along the side 9 and rear 8, the walls are in contact with the sides of the ice pan only at the bends 15. Thus,

' there is a clear aassac'e under the ice chamber wall to the refrigerator drain 16.

The ice pan 12 is placed in the refrigerator, and supported by the wooden ice bottom 17 provided therefor. The metallic walls are secured at their upper portion to the strips 5 where strips are used and to the upper cross member in the absence of strips. From the point at which they are secured, the walls slope away from the strips to enter the ice pan at their lower edge. Consequently, the metallic ice chamber walls are in contact with the strips or refrigerator wall only for a short distance at the upper portion thereof where condensation is negligible.

3. A refrigerator comprising a wall including a heat insulated lining absorptive to moisture, vertical spacing strips secured to the inner face ofthe wall, a drip pan for the ice chamber having the side wall adjacent said lining sloping outwardly into contiguity with the spacing strips, and a metallic chamber wall supported at its top against the spacing strips and sloping inwardly at its bottom away from the strips and resting with its bottom edge upon the said inclined side wall of the drip pan, the said inclined. side walls of the drip pan being bent around the spacing strips to form passages under the bottom edge of the metallic ice chamber wall.

In witness whereof, I hereunto subscribe my signature.

' From the foregoing description, it will be Y apparent that any water condensing on the outer surface of the metallic walls will flow downward along the surface of the wall to the side of the ice pan and under the wall to the refrigeratorv drain.

itis obvious that various changes may be made in the'construction shown in the drawings and above particularly described within the principle and scope of my invention as expressed in the appended claims.
